Linux boot from SAN disks to Internal disk

Folks,

I need some help, We have a Linux host which is currently running/booting
from a disk which is allocated from a SAN. We have to move bootable disk
from SAN to internal disks. We have used dd and created a copy of the SAN
disk to Internal disks. However, when we boot it says:
rootvg not found.

We have used clonezilla but it did't give work as expected.

I think there should be way around, can someone provide some hint or way
around this?

Regards,
Yash
